1.

The Vcc values are the expected voltage measured at the processor die.

2.

The Dual-Core Intel® Xeon® 7100 series / Dual-Core Intel® Xeon® processor 7000 sequence entry is 

required for backward compatibility for VR ‘modules’ only using the EVRD/VRM 10.2, but the VRM11.0 

should be backward compatible with VRM10.2 platforms, as modular VRs can be transferred from one 

platform to another.

3.

For VRM 11.0 mode, VRM_Pres# and VR_ID# should be held LOW for all combinations as described in 

.

The voltage ranges shown in 

 include the following tolerances:

• Initial DC output voltage set-point error.
• Output ripple and noise.
• No-load offset centering error.
• Current sensing and droop errors.
• Component aging affect.
• Full ambient temperature range and warm up.
• Dynamic output changes from minimum-to-maximum and maximum-to-minimum 

load should be measured at the point of regulation. When measuring the response 
of the die voltage to dynamic loads, use the VCC_DIE_SENSE and VSS_DIE_SENSE 
or VCC_DIE_SENSE2 and VSS_DIE_SENSE2 pins on the processor socket with an 
oscilloscope set to a DC to 20-100 MHz bandwidth limit and with probes that are 
1.5 pF maximum and 1 MW minimum impedance.

• Variations of the input voltage.
